He was a Scottish-American minister, philosopher, and college president. He studied at the University of Glasgow and at the University of Edinburgh (M.A., 1833). In 1834, he became a minister of the Established Church of Scotland and later the Free Church of Scotland. While a student, he developed a serious interest in natural theology and philosophy which culminated in his first book, "The Method of the Divine Government, Physical and Moral" (1850). He became Professor of Logic and Metaphysics at Queen's College, Belfast (1852-1868). In 1860, he published his most important book "The Intuitions of the Mind Inductively Investigated". The Presbyterian-founded College of New Jersey (now Princeton University) chose McCosh as its president in 1868. He expanded the faculty, the program, and increased enrollment and financial support.
